The device forming'the subject matter of crating mechanisms, to wit, 'a mining ma-' ingiup, firstythe mining machine,'such views 6 and 9 make it evidentthat the this;' app1ication includes two principal coop- I the present-,Lis designated as a whole by'the i nun'ieral 1; the frame carrying a prime vmover, suchas an electric motor 10, the shaft of the motor carryingand operatinga pinion9. 4

' A; main auger shaft extends lengthwise-of the machine. The auger shaft 2rotates, and

ithas, also, a slight longitudinal reciprocatory. movement. As seen in Figure 6 at 50,

the rear endof the auger shaft 2 is mounted to slide-andito rotate in the'frame 1. The

auger 'shaft =includes an enlarged intermedi- :atepart 32 mounted in the frame of the ma: chine and provided with an oil groove 33 0f 7 1 spiral formythe construction being such that the groove receivesoil from a reservoir- 36:

Forthe lubrication of the part 34, thielsame in theframe, to lubricate the part 3210f the auger-shaft, as the augershaft slidesa d ro- ,tates; The main auger shaft comp'ri's'esfiam' is provided with, a spiral groovess distriblltil'iggoilwhidh is" delivered upon the part 34 ofzthe augershaftsthrQughanoiL-duct 37 1 thatextends back to the oil reservoir 36. The forward P on f the part 34; of the auger of'the auger shaft is connected atv 89, byv

shaft cooperates with a bearing 38 in the frontend of the frame 1. The forward end threading or otherwise, to an auger 40.

The main auger 40 has a two-part spiral flange 42 (Fig'ure 7 the constituent mem bers of the flange 42 eing connected by pairs of cross pins 41. Cutters 43 project out- .wardly beyond the flange 42, the cutters abutting against the body of the auger .40 and against one of the pins of each pair,'the cutters being hooked under the other pin 41 of each pair, a secure but releasable mounting for the cutters being provided, as any one can see readily when Figure 8 of the drawlngs 1s I noted. It appears from Figure 4 that the forward end of the auger shafthas bifurcations 51recei-vi1ig the rear end of an auger tip '52,'the parts l'and 52 being connected at 53, to hold the auger tip in place. I

Referring to Figures '6 and 17, it may be stated that the pinion 9 on the shaft of the motor meshes with a gear wheel 7.

Through the gear wheel 7 extends the tubular clutch-member 59 canturn with respect to the hub 54 and the pinion 55', but the clutch memher 59 is splined at 61 to the main auger shaft 2, sothat although the auger shaft can move I endwise in the clutch member 59, the shaft 2 and the clutchmember 59 must participate in a commonrotation. A clutch member 62 is journaled in a cuff 63 located within the bearing 56. In one end of the clutch member 62'tliere is a clutch 64', andin the opposite end of the member .62 there'is a clutch65. The clutch member 62 is splined at 66 into the hub Y 54 of the pinion for relative sliding movement. The clutch member62 has a circumferential groove 67 for the rotatable reception of a shift ring 68 that is under the governance of a hand lever 15 fulerumed on a segment 17 carried by the framel, the hand lever 17 having a latch mechanism 16 adapted to cooperate with the segment.

iVheu the clutch member 62 is shifted to the left in Figure 6 by means of the ring 68 and the lever'15, the clutch elements 65 of the member 62 cooperate with the clutch elements 69 of the clutch member 59. Then there is established a driving train for the main auger shaft'2. including the motor 10, the pinion 9, the'gear wheel 7, the tubular hub 54 0f the pinion (because the hub 54 is keyed at 57 to the gear wheel 7), the spline66, the clutch member '62, the clutch element 65, th'eclutch elementGO, the clutch'member 59, the spline 71 on the truck 70, a sprocket wheel 61, and the main auger shaft 2. As a result of this connection rotation is imparted to the auger shaft 2. The pinion 55 is rotated also, and the function of the pinion 55 will be explained hereinafter. By shifting the lever 15 into a neutral position, the clutch member 62 may be moved into such a position that the clutch elements will be disengaged from the clutch elements 60, and, then, rotation will not be imparted to .the clutch member 59 and to the auger shaft 2. It may be stated profitably at this place that by shifting the lever 15, the clutch member 62 may be moved far enough to they ri ht in Figure 6 so that the clutch 64 of the member 62 will be engaged with a clutch 69 on the truck 70, when the mining machine is mounted on the truck 70, as shown in Figure 4 of the drawings. The driving train for the truck includes the motor 10 of the mining machine, the pinion 9 of the motor, the gear wheel 7 the key 57, the hub 54, the spline 66, the clutch member 62, the clutch member 64, the clutch 69 a shaft is (Figure 2) on theshaft, a sprocket chain 73 engaged with the sprocket wheel 72 and connected operatively with the axle 74 which carries one set of truck wheels 75, motion being transmitted from the axle 74 to the other axle 76 and the corresponding wheels 77by a sprocket chain 78 which is shown in Figure 4.

On-the rear end of the truck [(0 there is journaled a reel 162 which isdriven by a chain and sprocket connection 163 from the shaft 71, suitable clutch mechanism 164 being suppliedhso that the shaft 71 will either operate the chain 7 3 and propel the truck, or rotate the reel-162. The reel 162 carries the cable 165 which contains the conductors for the motor 10.

The pinion 55 meshes with a gear 6 on a shaft 79 extended lengthwise of the frame 1 and journaled thereon. The shaft 79 carries a beveled gear 80 meshing with a beveled gear 81 (Fig. 13) on a countershaft 82 disposed transverselyof the frame of the machine and supported for rotation thereon. A pinion 83 is fixed to the countershaft 82 and meshes with a gear wheel 84 mounted to turn on a shaft 18 journaled on the frame 1.

The gear wheel 84 meshes with a pinion 87 carried by a shaft 88 which is mounted to slide endwise and to rotate on the frame 1, the construction being such that the pinion 87 may be shifted out of mesh with the gear wheel 84 when desired. The pinion 87 meshes with a gear 89 on a shaft 90 journaled in the framel. 'On the shaft 90, a support 91 is mounted to swing, and in the support 91 a shaft. 92 is journaled, the shaft being journaled also in ,a tubular bearing 93 having a foot 94 mounted to rotate in the support 91 and held on the support for rotation by set screws 95 extended into a circumferential groove 96 in the foot 94. It is possible to j igw gooe advance the set screws and holdthegfoofi 94 and the bearing 93 against rotation The lower end 'of the shaft 92 isgsoperatively coni nected with-the shaft '90Iby' beveled.gears 971 Onthe'upper endof the bearing 93 there isa guide casing98 (Figsi13 audit)- in an augei shaft 99 is mounted to slide longi tudinally andt'o rotate, the auger shaft carrying an'auger 100 which isused'for boring blast holes. The auger shaft 99 is splined at 101"(-F-ig. 13) into a beveledpinion .102

located within the casing 98,- the pini'on 1'02 meshing with beveledxpinion 103 on the shaft 92. Therasing 98 has adepending" bracket 104, as shown in Figure 1, and'tothis bracket ispivoted a longitudinally extensible prop 105 (Fig. 12) adapted to cooperate with I the frame work 1 of theinachine to hold the auger 100 at any desired angle, as shown'in Figure 1. The rear-end of the auger-shaft '99'isjourn'aled n 'a shoe 1 0.6 provnleduuth a handle 107, the handle serving as an anchor for a flexible element108 which is passed across a sheave-109journaledin'a bracket 110 on the sideof th'e' bearing 93. The flexible element 108 is operated by means'which will :be described hereinafter, but'it will be obvious-that the flexible element 108' serves as a means foradvanoing the auger shaft 99 and the auger 100. The auger shaft 9 9qis rotated by'a train of elements comprising the beveled pinion 102, the beveled pinion 103., the shaft 92, the beveled pinions 97,the

shaft 90, the gear .89, the pinion 87, the gear wheel 84', the pinion 83, the countershaft 82-,

the beveled gear 81, the beveled gear 80, the shaft 79-, the gear 6, the pinion 55, and the gear wheel 7, the pinion 9, and the motor 10.

' Theoperation of the supplemental auger shaft 99may be stopped by shifting the pinion 87'sidewise (Fig. 13). The'auger shaft-99 'bearing member 93 is adjustably'held for rotation,at 95'96, intheupper art, fth support 91; g-.5 I g The shaft 79 carries a jworm 111 meshing with a worm wheel 112 which is connectediat '114 to the ,shaft 18} Theworm wheel 112 has an eccentric 1'15, 1 ai1dj-an eccentric 116.;is

secured at-117 to the shaft 18, as indicated in Figure 13. The eccentrics 115 and 116 ccoperate with straps 18 on arms "119 that are pivoted at 120 to a crosshead' 121 theends 122 of which slide on supports sides ofthe casing of the machine. The main auger shaft 2 is journalecl in the cross head 121 but is held against longitudinal movement therein by collars 124011 the shaft 2.

Longitudinal reciprocation isimparted to "126 meshes with a gear .128. and1128 each have a web 129 located between 123 at the the shaft .2 by .a trainof parts including the motor 10, the pinion 9, the gear wheel 7, the

pinion 55-, the gear 6, the shaft 79, the worm 11 1, the Wormwheel 112,-theshaft 18, the [eccentrics 115 and k V 116, the straps 118, the arms 119, the cross head 121,.and thecollars 124. It is evident that the main auger shaft ill 2 and the, auger'40 havea compound move-1 ment in thatv they rotate and slide longitudinally... IA clutch member 85 isslidable on the shaft 18, andf the shaft 18 is'rotatable in the clutch member. iThe clutch member 85 is slid by a shifting mechanism 86 which. is accessible from Without the frame '1, as. shown in. Fig. 6. The clutch .85 is supplied at one" end with a pinion 125, and at the other end with 7 a pinion 126. The pinion 125 meshes with agear127 .(Figures 9 and 16.) p I The gears 127 a fixed abutment 130 and a movable'clam'p 131, the abutment and the clamp being car- ;ried by ashaft 132. The abutment 130 is secured. to the shaft 132 against --movement thereon,but the clamp 131 is-splined at 133 and the pinion longitudinally thereof and against rotation to the shaft 132,. to slide toward and away from the abutment 130.. The shaft 132 is journaledin bearings 135 on the frame 1, and the clamps131 have hubs 136' that are journaled in bearings 134 on the frame-1, The

hubs 136 of the clamps 131 have flanges 137 j between which extends the tapered. part .138

(Figu're6) ofzailever, 139 which is 'fulcrumed at 140 on'the framework of the machine. A

link 141 is pivoted to theupperv end of the lever 139and carries a handle 142 which is accessible from theoutside of the framework of the machine The link141-is connected tov a retractile spring 143' that is anchored at 144' upon the machine frame.

A pinion 145and a pinion 146 are loose on.

the shaft 132, the pinion 145 being adapted i to be connected to the shaft .132 -bya clutch 147 under the control ofa lever 148., and the pinion. 146 being adapted to be 'conneeted to the shaft 132. by aclu'tch149 under the conframework of the machine.

"The pinion 146 mesheswith a gear wheel 1'51, and the pinion-:145 meshes with a gear flwheel 152,-thegear, wheels 151 and 152 being vmounted on a sliaft 153- that is journaled in bearings 154 on. the frame of the machine. The gear wheel152 is secured to aidrum 155,

156'.- It mayhere be noted that the flexible element 108; which controls the longitudinal l advancement of the auger shaft 99 of Figure l-is wound about thedrum .156. About the drum .155 iswound a flexible element 157 which may be engagedabout any desired number of a group of pulleys 158 on the matrol of a'lever.150which,'like thejlever 148, is fulcrumed on any accessible-part of the andthe gear wheel 151; is secured to a drum which mining machine may. be slid when the skid is lowered as in Figure'2'. The flexible element 157 may be connected to a hook 160 on the side of the skid, to raise the skid I out of the way, af-terthe mining machine has been mounted on the tr'uck1 as depicted in Figures 4 and 5. Reverting to Figure 15, the drum 155 and the gear wheel 152 may be connected at 161 to the shaft 153, but the gear wheell51 and the drum 156turn on the shaft 153.

The clutch -may be shifted .endwise by the mechanism shown" at 86, to connect the clutch either'with the'worm wheel 112 or with the gear'wheel 8 in Rotation, thus, can

i be imparted to the clutch 85 either from the train that operates the supplemental auger 99 in Figure 13, or by the'train (including the worm wheel 112), that imparts longitudinal reciprocation to the main auger shaft 2.- When the clutch 85 is rotated, the pinion 125 on theclutch 85, drives the gear wheel 127, or the pinion 126 on the clutch 85 drives the gear wheel 128, rotation. in either event, being'imparted to the shaft 132. The operator, then, by means of thelever-150, the clutch 149, the pinion 1 16 the gear wheel 151, and the drum 156, can operate the'flexible element 108, to feed the supplemental auger shaft 99 of Figure 1: or, by means of the lever 148, the clutch'1 i7, the pinion 1 45, the

V gear whee]. 152,"a nd theflexible element 157,

the operator'can, move the machine about, it being recalled that the flexible element 157 can be anchored and arranged around any of the pulleys 158. The lever 139 may be tilted more or less, to vary the amount that the part 138 of the lever extends between the flanges 137 of-Figure 16, thus varying the gripof the clamps 131 on the webs 12 9 of the gears 128 and adjusting the speed with which the flexible elements 108 or 157 areftaken in or paid out. p r The operation of the machine has-been dealt with hereinbefore stepfby step, and a brief'rsume' at this point will sufiice. 1 The auger-shaft 2 can rotate and move longitudinally, the supplemental auger shaft 99 of Figure 1 may be tilted vertically, rotated onits axis, swung with respect to a transverse axis, and be'fed longitudinally, and the machine can be loaded'on the truck and be caused to propel the truck it being possible,

through the instrumentality of the-drum 155 and the cable 157to haul the machine around asdesired, with respect to the work, when i the machine is'i-n theposition shown in Fig ure 1;
